Efficacy of Long Term Plavix Therapy Post Angioplasty

April 16, 2020 updated by: Javad Kojuri, Shiraz University of Medical Sciences

Evaluation of Safety, Benefits and Complications of Long-term Dual Antiplatelet Therapy in Patients With Angioplasty

1010 patients post stenting were enrolled to receive Plavix more than 12 months and less than that and rate of bleeding, complication and major cardiovascular adverse events ( MACE) were compared to evaluate safety and feasibility of long term Plavix therapy post stenting.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

1010 patients from registry of angioplasty and stenting in Shiraz and Baghiatolah hospital were enrolled and long term Plavix therapy more than and less than 12 months were compared between two groups of patients prospectively and rate of major adverse cardiovascular events ( MACE) (death, myocardial infarction, cerebrovascular accidents and revascularization) and rate of bleeding were compared between 2 groups.Syntax score and American heart association ( AHA) score of coronary involvement were measured and MACE was compared to these scores.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 12 months
number of patients with major bleeding need transfusion
12 months
Number of Patients With Myocardial Infarction Need Hospital Admission
Time Frame: 12 month
The number of patients with myocardial infarction need hospital admission
12 month
Number of Patients With Central Vascular Accidents Proved by CT Scan
Time Frame: 12 months
